Flash CS4 text color easing effect

Code Detailed:

[SWF (backgroundcolor=0x000000,width=550,height=400)]//set scene background color, size

var r:uint=0,g:uint=0,b:uint=0;//declares unsigned integer variables r, g, B, and the initial value is 0

var color:uint,targetr:uint,targetg:uint,targetb:uint;//declares unsigned integer variables color, targetr, TARGETG, TARGETB

var filtersco:uint,filtersr:uint,filtersg:uint,filtersb:uint;//declares unsigned integer variables Filtersco, FILTERSR, FiltersG, FiltersB

Var glowf:glowfilter;//declares a light-emitting filter class instance GLOWF

var matrix:matrix=new matrix ()//declaration of a matrices class instance matrix

Matrix.creategradientbox (550,200,0,0,0)//Set vector graph gradient fill required matrix style (width 550, height 200, rotation 0,x direction translation 0,y Direction translation 0)

var sh:shape=new Shape ()//Declare a vector diagram class instance sh

Sh.graphics.beginGradientFill (GRADIENTTYPE.LINEAR,[0XFF0000,0XFFFF00,0X00FF00,0X00FFFF,0X0000FF,0XFF00FF, 0xff0000],[1,1,1,1,1,1,1],[0,42,84,126,168,210,255],matrix)//Set gradient fill style (linear gradient, color block color, transparency, color block position, matrix)

Sh.graphics.drawRect (0,0,550,200)//Draw rectangle in sh (upper left corner coordinate (0,0), width 550, height 200)

Sh.graphics.endFill ()//End Fill

var bmd:bitmapdata=new BitmapData (550,200)//Declare a bitmap data class instance BMD (width 550, height 200)

var bim:bitmap=new Bitmap (BMD);//Declare a bitmap wrapper class instance BIM, for packing BMD

Bmd.draw (SH);//bitmap BMD for vector image sh photo

AddChild (BIM)//Add bitmap BIM to display list

var txt:textfield=new TextField ()//Declare a text class instance txt

AddChild (TXT);//Add text TXT to display list

Txt.defaulttextformat=new TextFormat ("Chinese amber", 60);//Set text formatting (font, size) Note This setting does not work until it is placed in front of the content

txt.text= "Special software station welcome you!"; /text content

txt.autosize=textfieldautosize.center;//Text txt auto resize and center align

txt.x=stage.stagewidth/2-txt.width/2;//the x-coordinate of the text, placing the text in the middle of the stage

txt.y=stage.stageheight*3/4-txt.height/2;//the y-coordinate of the text, place the text in portrait 3/4

AddEventListener (event.enter_frame,frame);//Add frame-frequency event listening, calling function frame

function Frame (e) {//define Frame frequency event function frame

Color=bmd.getpixel (Mousex,mousey);//color gets the color of the pixel at the bitmap mouse

Targetr=color>>16;//targetr gets the value of the red channel in color

TARGETG=COLOR>>8&0XFF;//TARGETG gets the green channel value in color

Targetb=color&0xff;//targetb gets the value of the blue channel in color

R+=uint ((targetr-r) *0.03)//r per frame increased by 0.03 times times the difference between TARGETR and R

G+=uint ((targetg-g) *0.03)//g per frame increased by 0.03 times times the difference between TARGETG and G

B+=uint ((targetb-b) *0.03)//b per frame increases by 0.03 times times the difference between TARGETB and B

txt.textcolor=r<<16|g<<8|b;//the R, G, b synthetic color value to text txt

FILTERSR=0XFF-R;//FILTERSR gets the difference between 0xFF and R

FILTERSG=0XFF-G;//FILTERSG gets the difference between 0xFF and G

FILTERSB=0XFF-B;//FILTERSB gets the difference between 0xFF and B

filtersco=filtersr<<16|filtersg<<8|filtersb;//FILTERSR, FILTERSG, FILTERSB synthetic color to the value of FiltersCo

Glowf=new Glowfilter (filtersco,1,8,8)//Glow filter GLOWF instantiation (color, transparency, X-direction blur, Y-direction blur value)

txt.filters=[glowf];//text Apply a glow filter

}
